ROLLER FOR COTTON-GINS.

Specification of Letters Patent.

Patented Mar. 1, 1921.

Application filed September 23, 1919. Serial No. 325,633.

To all whom it may concern:

Be it known that EDW'ARD R. TISCHER, a citizen of the United States, residin at Houston, in the county of Harris and tate of Texas, have invented certain new and useful Improvemenets in Rollers for Cotton- Gins, of which the following is a specification.

This invention relates to new and useful improvements in a roller for cotton gins.

One object of the invention is to provide a device of the character described especially constructed to strip the lint cotton from the cotton seed.

Another object of the invention is to provide a roller which is provided with inset friction plugs which engage with the lint and by friction, strip the same from the seeds, said plugs being inset at a forwardly inclined angle and under compression, so as to secure them against displacement during the operation of the roller.

A further feature of the invention resides in the provision of a hollow roller equipped with internal suction fans which induce an air current through the roller to keep the same comparatively cool.

\Vith the above and other objects in view, the invention has particular relation to ccrtain novel features of construction, and use, an example of which is given in this specification and illustrated in the accompanying drawings, wherein:

Figure 1, is a side elevation of the device.

Figs. 2 and 3 show the ends thereof, re spectively.

Fig. 4 shows a cross sectional view, and

Fig. 5 shows an enlarged end view.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numeral 1, designates a hollow from becoming too hot by reason of the friction thereof against the cotton.

The drum has relatively thick walls, which are provided with peripheral rows of deep sockets 4;, to receive plugs 5, of cork or other similar material. These plugs are set at a forwardly inclined angle, and are highly compressed when inserted, so that they will not become displaced in operation, and their outer peripheries are flush with the outer periphery of the drum and thus have a greater friction surface than would be the case were they set at a radial angle.

In operation, the drum is located adjacent a shoe 6, arcuate in cross section, to con form to the contour of the drum, and held in place by the long blade 7 as shown in Fig. 4. The seed cotton is fed onto the drum and carried around by it, the seeds being arrested by the upper edge of the shoe 6 and the lint being stripped from them, by the friction of the plugs 5, and carried on around EDWARD R. TISCHER.
